Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Anticipated renal transplant within 6 months
  • Previous dialysis access graft in the operative limb unless the aXess graft can be placed more proximally than the previous failed graft
  • Previous enrolment in this study

Other illness

  • History or evidence of severe cardiac disease (NYHA Functional Class IV and/or EF \<25%), myocardial infarction within six months of study enrolment, ventricular tachyarrhythmias requiring continuing treatment, or unstable angina
  • Uncontrolled or poorly controlled diabetes
  • Any active local or systemic infection
  • Known active bleeding disorder and/or any coagulopathy or thromboembolic disease
  • Allergies to study device (nitinol) or agents/medication, such as contrast agents or aspirin, that can't be controlled medically
  • Any other condition which, in the judgement of the investigator would preclude adequate evaluation for the safety and performance of the study conduit
    • Intra-operative exclusion criteria:
    • 1\. Unsuitable anatomy to implant the aXess graft (e.g. target vein and/or artery diameter smaller than anticipated; severe calcification)

Lab values

  • Reduced liver function, defined as: \>2x the upper limit of normal for serum bilirubin, International Normalized Ratio (INR) \>1.5 or prothrombin time (PT) \>18 seconds

Other

  • Known heparin-induced thrombocytopenia
  • Known or suspected central vein obstruction on the side of planned graft implantation
  • Subject is participating in another study
  • Pregnant or breastfeeding woman or woman in fertile period not taking adequate contraceptives

Who the study is looking for

  • Subjects with end-stage renal disease (ESRD) who require placement of an AVG in the upper extremity to start or maintain hemodialysis therapy
  • At least 18 years of age at screening
  • Suitable anatomy (e.g. a target vein with a minimum diameter of 5mm) for the implantation of an aXess graft
  • The patient, or legal representative, has been informed about the nature of the study, agrees to its provisions, and has provided written informed consent
